What are the key features of TSM-127-01-SM-DH-A-P-TR?
- 54-position single-row SMT terminal strip on 0.100" (2.54mm) pitch for dense multi-signal board-level interconnect
- Dual-height (DH) body design provides clearance for stacked connectors or taller adjacent components in multi-board assemblies
- Tape-and-reel (TR) and polarized (P) options enable error-proof automated SMT assembly in high-volume production
What is TSM-127-01-SM-DH-A-P-TR used for?
The TSM-127-01-SM-DH-A-P-TR is suited for FPGA mezzanine cards, processor carrier boards, and modular industrial control systems where 54 signal lines must be routed through a standardized 0.100" pitch terminal strip on a single-row SMT footprint. Its polarization feature also reduces assembly errors in manufacturing environments where board-to-board stacking connectors are installed by hand or by automated pick-and-place equipment.

Frequently Asked Questions
What position count and pitch does TSM-127-01-SM-DH-A-P-TR offer for PCB connector applications?
The TSM-127-01-SM-DH-A-P-TR provides 54 positions on a 0.100" (2.54mm) pitch single-row surface mount terminal strip. This 54-pin configuration suits processor breakout boards, FPGA I/O headers, and multi-channel signal distribution interfaces where more than 38 but fewer than 66 contact positions are required in a standard 2.54mm grid connector footprint.
How does the SM (surface mount) and DH (dual-height) combination of TSM-127-01-SM-DH-A-P-TR affect its application in stacked board designs?
The SM designation confirms this is a surface mount connector for reflow soldering, eliminating through-hole drill requirements and saving PCB layer routing. The DH (dual-height) body adds extra vertical clearance—typically several millimeters above the PCB surface—which allows the mating header or daughter board to bridge over components populated within the footprint envelope, enabling compact 3D stacked assemblies in embedded computing or modular industrial systems.
What does the P (polarized) feature on TSM-127-01-SM-DH-A-P-TR prevent in high-volume PCB assembly?
The P polarization key on TSM-127-01-SM-DH-A-P-TR blocks reversed insertion into the mating receptor by occupying one of the 54 positions with a physical obstruction. In high-volume SMT assembly lines processing hundreds of boards per shift, a misoriented 54-pin connector can damage all 54 contact pairs; the polarization feature prevents this by making incorrect mating mechanically impossible, reducing field return rates and assembly rework costs.
How does TSM-127-01-SM-DH-A-P-TR compare to the 38-position TSM-119 and 66-position TSM-133 in a signal-count selection?
TSM-127-01-SM-DH-A-P-TR with 54 positions sits between the 38-position TSM-119 and the 66-position TSM-133 series. When a design needs between 39 and 54 signals—such as a 32-bit address bus with select and control lines—the 54-position strip avoids the unused pins and excess PCB length of the 66-position variant while providing more contacts than the 38-position strip on the same 0.100" pitch grid.
